dict() function in Tornado Templates.

[Zippoxer]

Jinja2 has dict() function which creates a dictionary (which can be
iterated): http://jinja.pocoo.org/docs/templates/#dict
Tornado templates has list() only but dict() is missing.
Can tornado templates create a dictionary? And if they can't, how can
I add this functionality?

[Zippoxer]

Okay. There is some kind of solution.

I noticed I can do this:
{% for k, v in [("Name", current_user), ("Level", "1"), ("City",
"Carlin"), ("Health", "100/100"), ("Mana", "100/100")] %}
{{ k }} = {{ v }}<br/>
{% end %}

But not this:
{% for k, v in [("Name", current_user),
("Level", "1"), ("City", "Carlin"),
("Health", "100/100"),
("Mana", "100/100")] %}
{{ k }} = {{ v }}<br/>
{% end %}

Conclusion: I must write all of the elements in one line :\

All built-in python functions (including list() and dict()) are accessible in tornado templates.  To add new functions to the template namespace, you can use the ui_methods application setting or pass keyword arguments to the render method.

This doesn't work :(
Tornado templates doesn't support named parameters? (So I can't create
a dict(key="value"))

[Ben Darnell]

Tornado templates mostly just get turned into python code, so whatever works in python should work in the template (including named parameters, etc).  You'll need to provide more information about what's not working.

this works:

{% for k, v in dict(bro='it works').items() %}
the key: {{ k }}<br/>
value: {{ v }}
{% end %}

Ohh I forgot you should use .items(), thanks =]

Okay, so this works:
{% for k, v in {"name": current_user, "level": "1", "city": "Carlin",
"health": "100/100", "mana": "100/100"}.items() %}
<tr>
<td class="key">{{ k.title() }}</td>
<td class="value">{{ v }}</td>
</tr>
{% end %}

But this doesn't:
{% for k, v in {"name": current_user,
"level": "1",
"city": "Carlin",
"health": "100/100",
"mana": "100/100"}.items() %}
<tr>
<td class="key">{{ k.title() }}</td>
<td class="value">{{ v }}</td>
</tr>
{% end %}

the {% for %} statement can't be divided to more than one like.
